  1. Imaging of abdominal aortic aneurysm disease activity and implications for endovascular aneurysm repair

    Debono, SamuelThe University of Edinburgh2024

    BACKGROUND: Abdominal aortic aneurysm treatment pathways are initiated when an aortic size threshold of 55 mm is reached as this signifies a high annual risk of rupture due to presumed active aneurysm disease. Endovascular aneurysm repair (EVAR) is one treatment modality which reduces the …

  2. Risk Factors in Abdominal Aortic Aneurysm

    Cho, Jun Seok2017

    The mortality rate of ruptured abdominal aortic aneurysm (AAA) has been reported to be as high as 85%. Evidence suggests that ultrasound screening reduces overall and AAA-related mortality. The aim of this study was to identify and document risk factors for AAA from the largest Welsh cohort …

  3. Molecular genetics of abdominal aortic aneurysm

    Chinien, GanessenKing's College London2012

    Abdominal aortic aneurysm (AAA) is a common disorder and a major cause of death. Pathological processes involved in AAA formation include inflammation, proteolysis, angiogenesis and apoptosis. It has also a strong familial predisposition with linkage studies identifying chromosomes 19q13 and 4q31 …

  5. Abdominal Aortic Aneurysm – Different Aspects on Screening

    Zarrouk, MoncefUnit for Clinical Vascular Disease Research2015

    Abstract Abdominal aortic aneurysm (AAA) is a hideous life threatening disease that most often is asymptomatic until it ruptures. Ruptured abdominal aortic aneurysm (rAAA) is a painful and serious predicament with a mortality of 80-90%. Half of the patients die before arriving to hospital, leaving …

  6. Sensitivity of Hostile Hemodynamics to Intracranial Aneurysm Geometry

    MacDonald, Daniel Edward2022

    An intracranial aneurysm (IA) is an abnormal outpouching of an artery in the brain and is thought to be present in about 1 in 30 adults. Rupture of an IA is a devastating event leading to death or disability in most cases. To supplement clinical treatment decisions, researchers have turned to …

  8. Genetic dissection of essential hypertension and familial intracranial aneurysm

    Brain, Nicholas John RichardUniversity of Glasgow2004

    The studies of hypertension, described herein, combined complementary strategies to examine the relevance of human chromosome 5q31.1-qter to blood pressure as a quantitative trait, and hypertension as a qualitative trait. This distal region of chromosome 5 was focused upon due to its implication by …

  10. Collagen structure within aneurysm tissue in bicuspid aortic valve patients

    Bozorgmehr, ZahraGraduate Studies2025

    Aortic aneurysms pose a substantial clinical problem, especially in individuals with bicuspid aortic valve (BAV) disease, as aneurysm formation is 50% more common in these populations. Although the exact cause of aortic aneurysms in BAV patients is still unknown, a growing body of research points …

  13. Multiphysics Computational Model of Fluid Flow and Mass Transport in Aneurysm

    Cupac, Tanja2021

    <p>The abdominal aortic aneurysm is progressive, asymptomatic, and can eventually lead to rupture which is a catastrophic event leading to massive internal bleeding and possibly death. AAA cases have been characterized by the development of an intraluminal thrombus (ILT). The ILT correlates with …

    <p>Ascending thoracic aortic aneurysm (aTAA) is a potentially lethal disease which grows gradually over time and may lead to aortic dissection and rupture. Currently, aTAA surgical repair using Dacron graft is a well-established treatment. In addition, surgical adhesives are frequently used in the …
